Benefits of technology
The present invention provides better methods and devices for performing abrading operations. Specifically, the invention provides an abrading device with a pair of rotating abrading members that move in opposite directions. Each member has an annular surface that abrades the surface being treated. The device can also have a driving source that rotates both members at the same time. This design allows for smoother and more efficient abridging of surfaces.
Problems solved by technology
Presently when performing abrading operations according to manual methods, an operator freely utilizes an unconstrained abrading tool to remove material from the tire.
To further complicate matters in either manual or automatic applications when using an abrading device having two rotating abrading members, an operator may endure additional strain when having to translate the abrading tool across a tire surface while both abrading members rotate in the same direction to resist such translation.

Embodiment Construction
[0024]Particular embodiments of the present invention provide an abrading device (or also referred to as “tool” herein) having a pair of abrading members (i.e., a dual head abrading tool) which counter-rotate to generally balance the abrading forces acting upon the tool and ultimately upon an operator as generated by the tool as the rotating abrading members engage a tire surface during abrading operations. The operator may comprise a user (i.e., a person) or a machine, where said machine may be automated or partially automated. When employing an abrading tool employing two or more rotating abrading members driven in the same direction, such rotation imparts significant forces upon an operator when translating the tool across a target surface. To generally offset or reduce these forces acting on a user or machine, the present invention provides oppositely rotating abrading members (e.g., abrading heads, disks, or wheels), where one rotates a first direction (e.g., clockwise) and the...

Abstract
Exemplary embodiments of the subject invention comprise methods and apparatus concerning balanced abrading of a tire surface by an abrading tool. Such an abrading tool may comprise a pair of counter-rotating, driven abrading members, each of the abrading members having a rotational axis generally extending laterally across the tool, the abrading members being spaced apart in a lateral direction of the tool by a desired distance, each of the abrading members having an abrading surface defined by at least one outer diameter, the abrading surface extending axially relative to the rotational axis of the abrading member, wherein each of the abrading has a shaft upon which each abrading member is arranged, each of the shafts being adapted to be driven by a driving source. The tool further includes a body to which each shaft and abrading member is attached.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates generally to methods and apparatus for abrading a surface of a tire, and in particular instances, abrading a surface of a tire in preparation for tire repair and patch application.[0003]2. Description of the Related Art[0004]It is commonly known to abrade a surface of a tire to remove desired material there from. For example, abrading operations may be performed along the tire tread, such as to improve tire performance or to prepare the tire for retreading. Tire performance may be improved, for example, by improving conicity. In performing retreading operations, abrading operations are performed to generally remove a substantial portion of the pre-existing tread to prepare the tire carcass for receipt of a new tread.[0005]By further example, it is known to abrade an interior tire surface in preparation for applying a tire patch to repair a damaged portion of a tire. In preparing the tire for recei...
